1. Please keep the warranty card of this device properly. The warranty card has the factory number (and important
technical parameters) of the device. It has important reference value for future maintenance and new equipment.
2. During the warranty period, if the product is damaged due to the quality of the product instead of natural damage
such as man-made damage or lightning strike, enjoy free warranty; please do not repair it by yourself, please contact
us if there is a problem. Ebyte provides first-class After sales service.
3. Do not operate this station near some flammable places (such as coal mines) or explosive dangerous objects (such as
detonators for detonation).
4. Appropriate DC stabilized power should be selected, which requires strong anti-high-frequency interference ability,
small ripple, and sufficient load capacity; it is also better to have functions such as overcurrent, overvoltage
protection and lightning protection to ensure data transmission The radio works normally.
5. Do not use in working environments that exceed the environmental characteristics of digital radio stations, such as
high temperature, humidity, low temperature, strong electromagnetic fields or dusty environments.
6. Don't let the DTU continuously transmit at full load, otherwise the transmitter may be burned.
7. The ground wire of the DTU should be well connected with the ground wire of the external equipment (such as PC,
PLC, etc.) and the ground wire of the power supply, otherwise it is easy to burn the communication interface, etc .;
Do not plug or unplug the serial port with power.
8. When testing the DTU, you must connect a matching antenna or a 50Ω dummy load, otherwise it will easily damage
the transmitter; if the antenna is connected, the distance between the human body and the antenna should be more
than 2 meters, so as not to cause injury. Touch the antenna while transmitting.
9. DTUs often have different communication distances in different environments. The communication distance is often
affected by temperature, humidity, obstacle density, obstacle volume, and electromagnetic environment. In order to
ensure stable communication, it is recommended to reserve more than 50% Communication distance margin.
